    • A magnetic recording medium includes: tracks each including a magnetic recording section in which information is recorded and a non-magnetic-recording section in which no information is recorded; and nonmagnetic guide sections magnetically separating the tracks from one another. The non-magnetic-recording section is formed integrally with nonmagnetic guide sections. The magnetic recording medium includes at least one pair of a first region in which at least a portion of each of the respective non-magnetic-recording sections of first and second tracks and a portion of a magnetic recording section of a third track coincide with one another at a position along a direction in which the tracks extend; and a second region in which at least a portion of each of the respective non-magnetic-recording sections of the first and third tracks and a portion of a magnetic recording section of the second track coincide with one another at a position along the direction in which the tracks extend.
    • 磁记录介质包括:各自包括记录有信息的磁记录部分和不记录信息的非磁记录部分的磁道; 和非磁性引导部分将磁道彼此磁性地分离。 非磁记录部与非磁性引导部一体形成。 磁记录介质包括至少一对第一区域,其中第一和第二轨道的各个非磁记录部分的每一个的至少一部分和第三轨道的磁记录部分的一部分与一个第一区域重合 另一个沿着轨道延伸的方向的位置; 以及第二区域,其中第一和第三轨道的各个非磁性记录部分的每一个的至少一部分和第二轨道的磁记录部分的一部分在沿着方向的位置处彼此重合 轨道延伸。
